Medicaments for treatmenting colics

ABSTRACT

Medicament for treating colics comprising diphenhydramine-HCI, belladonna tincture, a buffer and flavourants as well as absolute alcohol, wherein the alcohol concentrate comprises between 2.8% and 3.2% by volume of the medicament.

[0001] A This invention relates to medicaments.

[0002] The invention is concerned with medicaments for use in treating babies and in particular to treating babies suffering from colic. Colic is a very widespread illness suffered by babies usually under three to four months of age. Infantile colic is a syndrome characterised by paroxysmal, excessive, and inconsolable crying without identifiable cause in a healthy infant. It is also called persistent crying in infancy and 3-month colic. The behaviour of colicky infants is a cause of anxiety and worry to their parents. Many medicaments for treating this source of discomfort in babies have been proposed but none, to our knowledge is wholly satisfactory.

[0003] According to one aspect of the invention there is provided a medicament for treating colic comprising diphenhydramine HCl, belladonna tincture, a buffer and flavourants as well as absolute alcohol and has been treated to increase shelf life, wherein the alcohol constituent comprises between 2.8% and 3.2%, and preferably 3.2% by volume of the medicament. Where the alcohol is a dilute form of alcohol e.g. alcohol BP 96.4% the amount of that dilute alcohol may be increased so that the actual alcohol content is as mentioned.

[0004] Conveniently the buffer is citric acid.

[0005] The medicament may be treated to increase shelf life by being bombarded by gamma rays. Alternatively and more usually the medicament is treated to increase shelf life by incorporating a preservative as a constituent. This preservative may comprise one or more of the following, viz methyl paraben, propyl paraben, aqueous chloroform, preferably in concentrate form, and alcohol and conveniently all of these ingredients. Another preservative which may be used is sodium benzoate. The alcohol in addition to being a preservative is also the solvent for the medicament. The methyl paraben conveniently comprises between 50 to 100 gm and preferably 100 gm per 100 l medicament. The propyl paraben conveniently comprises between 5 to 10 gm and preferably 10 gm per 100 l medicament.

[0006] The flavourant is preferably a sweetener. The sweetener may be a cyclamate or saccharine. Preferably however it comprises a berry, preferably raspberry, flavourant which conveniently comprises of the order of 50 ml per 100 l medicament. The sweetener may further or alternatively include syrup simplex which may conveniently comprise between 20 to 35 l and preferably 35 l per 100 l medicament.

[0007] The aqueous chloroform concentrate also serves as a preservative.

[0008] It will also be understood that the assqeous chloroform concentrate and belladonna tincture contain alcohol. The total amount of alcohol in the medicament is conveniently between 4.75% to 5.1% preferably about 5.1%. Accordingly another aspect of the invention provides a medicament for treating colic comprising diphenhydramine HCl, belladonna tincture, a buffer and flavourants and aqueous chloroform concentrate as well as absolute alcohol and has been treated to increase shelf life, wherein the alcohol content of the medicament comprises between 4.75% and 5.1%, and preferably 5.1% by volume of the medicament.

[0009] According to a further aspect of the invention there is provided a method of treating a colicky infant comprises feeding the infant a medicament as mentioned in any one of the preceding claims. The medicament is preferably administered to the infant in an amount of the of 1 ml per kilogram body mass with feeds normally four hourly with a maximum of 8 ml per dose.

[0010] An example of the medicament is given below, with the amounts set forth both for a single dosage amount and for the amounts for making 100 l. The names of the suppliers is given for identification purposes only. The ingredients may be supplied by others. Constituent Purpose Supplier Per 5 ml Per 100 l Diphenhydramine HCl Active Sweizerhall 3.125 mg 62.5 g Belladonna Tincture Active William Ransome 0.125 ml 2.5 l Absolute alcohol 99% Solvent Illovo 0.16 ml 3.2 l Citric acid monohydrate Buffer Medicolab 6.25 mg 125 g aqueous chloroform concentrate Flavourant Medicolab 0.025 ml 0.5 l methyl paraben Preservative Ethnichem 5 mg 100 g propyl paraben Preservative Protameen Chem 0.5 mg 10 g syrup simplex Sweetener Bush Boake Allen 1.75 ml 35 l Raspberry Flavour Sweetener Bush Boake Allen 0.0025 mg 0.050 l Poncho 4R Colourant Bush Boake Allen 0.27 mg 5.4 g Distilled Water Solvent Medicolab to 5 ml to 100 l

[0011] The total alcohol content of this example is approximately 5.1% by volume of the medicament. This is calculated as follows:— Absolute alcohol 0.16 ml × 99% = 0.1584 ml Aq Chlorof. Conc 0.025 ml × (60% × 90%) =  0.135 ml Belladona Tinc 0.125 ml × 65% = 0.0813 ml 0.2553 ml

[0012] Instead of using absolute alcohol, alcohol BP 94,4% may be used in which case a slightly greater amount may be used to have the same effect as absolute alcohol.

[0013] We have found that the raspberry flavoured sweetener is most satisfactory and provides in addition a pleasant fragrance to the medicament. However other flavoured sweeteners may be used such as strawberry sweetener.

[0014] All the ingredients used are as approved by the Medical Control Council of South Africa.

[0015] In tests carried out, it was found that about 77% of the patients showed moderate or excellent improvement when treated with the above medicament. Babies had high tolerance for the medicament. Only about 11% of the babies experienced adverse events regarded as possibly related to the medicament. The most affected body system was in the digestive system where constipation was caused. In addition we have found that excess nasal mucous has in a few cases been noted. These adverse events were mild to moderate in intensity. Most of the adverse events were resolved within a short time.

[0016] Care should be exercised in using the medicament in cases where the baby suffers from epilepsy or asthma or there is a family history of these illnesses.

[0017] The medicament may be altered as will be appreciated by those skilled in the art. However the alcohol content should not be increased above that mentioned above.
